DNA metabarcoding is transforming diatom-based environmental monitoring, yet its global application is currently hindered by significant  reference gaps. Many critical indicator taxa, particularly in North America, lack taxonomically validated sequences in DNA libraries. Our project addresses this limitation by hosting a three-day intensive workshop to train and connect researchers at the Iowa Lakeside Laboratory in May 2026

The network start-up focuses on bridging the gap between classical morphology and modern genomics. During the workshop, our early-career researchers will be trained in single-cell isolation and high-quality light microscopy. By pairing DNA sequences (rbcL and 18S V4 rRNA) with voucher-backed micrographs and herbarium specimens, we aim to generate a minimum of 14 new reference barcodes from the Iowa Great Lakes region. 

These data will be accessioned into NCBI GenBank and Diat.barcode, strengthening the DNA reference libraries necessary for accurate biomonitoring and ensuring that the next generation of diatomists are skilled in both traditional and molecular taxonomic approaches.
